0027739: Visualization, TKV3d - implement individual acceleration data structure for selection of 2D persistent objects
Low-level selection algorithms has been improved to explicitly support 2D
transformation persistent objects. This patch generally touches:
1) SelectMgr_SelectableObjectSet - the lists of objects has been split onto three
subsets (regular, 3d-persistent, 2d-persistent). Each subset has individual BVH
tree. The algorithms are now have more flexibility to update only those trees
that is really required for actual camera state.
2) SelectMgr_ViewerSelector - explicitly supports Eye space selection operations
on BVH tree for 2d-persistent subset. Change of camera position does not
anymore affect acceleration data structure (BVH tree) of 2d-persistent selectable objects.
3) Other classes from SelectMgr have been fine-tuned to provide appropriate API.
Porting notes:
This patch touches very low-level selection classes. If the low-level features were used
the following modifications may need to be considered for porting:
1) Iteration over objects of SelectMgr_SelectableObjectSet should now
be implemented with corresponding Iterator class.
2) SelectMgr_BaseFrustum::ScaleAndTransform and derived classes return
Handle(SelectMgr_BaseFrustum) instead of NCollection_Handle<> type.
0027842: Exception in intersection algorithm if FPE is switched on

while collecting the faces for building the solids;
2. BOPDS_DS - Making the check on coincidence of edges consistent with the intersection

0027804: Two breps cause intersections to loop for too long/infinitely
In ProjLib_ComputeApprox algorithm, compute correct parametric tolerance from the input 3D tolerance using surface resolution, in order to pass it to low-level 2D algorithm Approx_FitAndDivide2d (instantiation of the generic class Approx_ComputeCLine). Earlier 3D tolerance was used as parametric tolerance directly, which was a problem for surfaces with too small radius of curvature.
Also, eliminate redundant creation of the object of type AppParCurves_MultiCurve on each iteration in the method Approx_ComputeCLine::Compute.
The post treatment of the Edge/Edge intersections has been improved. Namely:
a. Making the procedure of sharing Edge/Edge intersection vertices consistent with intersection algorithm by enlarging bounding box of each vertex on half of Precision::Confusion();
b. Algorithm of computation of vertex tolerance (in order to cover tangent zone between Edges) has been changed for Line/Circle cases.

0027781: [Regression to 6.9.0] Exception in ShapeFix_Shape algorithm with option FixSmallAreaWireMode
The matter was that during checking wires of a shape for small area, non-outer wires were checked with constructing a new face with BRepBuilderAPI_MakeFace. If a face has location an edge from original face has no pcurve on the constructed face, which leads to exception in BRepGProp::SurfaceProperties. The fix constructs new face using EmptyCopy.
The method ShapeAnalysis_Wire::CheckSmallArea() has been changed so as to check area of the outer wire without hole-wires. API of this method has been changed, as the second argument theIsOuterWire is not needed any more.
The test cases have been updated, below are explanations of changes:
test de iges_2 G7
The fixed version leaves a wire in a face, but the master version considered it small and removed. The master version works wrong. It is because the face built with this wire has negative area, but the code in CheckSmallArea function does not get absolute value before comparing area with the tolerance. The left wire leads to splitting of the face on two, checkshape error in the face, and statshape faulty due to increased number of faces in the second pass.
test de iges_2 G2
The fixed version leaves a wire that is removed in the master version. The cause is the same as in G7 test case. However, here the problematic wire has very big tolerance. So, when the fixed version left it in the shape, the overall maximal tolerance became much greater than in reference data.
test de step_3 E6
In fixed version a really bad small wire is removed from the face, while in master version it is left and produces an error in checkshape report. So, it is an improvement.

The matter was that with starting point paased into intersector the walking line goes one point outside of the surface domain. Then during purging this extra point is removed from the line but its geometry is used for the last vertex. This makes a set of points invalid for approximation, and as a result we obtain the curve with reversed tangent direction at the end.

If this parameter is false than the step of removing of outside points is skipped, and the result line is not distorted.

0027448: BOPTools_AlgoTools::IsMicroEdge does not correspond to shape validity criteria
1. IntTools_ShrunkRange::Perform
The algorithm of building shrunk range on the edge has been redesigned to make this range as big as possible.
By new definition it has to have the length not less than Precision::Confusion().
Although, the possibility of splitting of the edge has been taken into account. If it is impossible to put
vertex on edge in such a way that the tolerance spheres of the edge's vertices do not intersect the tolerance
sphere of the putting vertex the edge cannot be split. This possibility is saved in the new field
IntTools_ShrunkRange::myIsSplittable. It can be checked by the corresponding method IntTools_ShrunkRange::IsSplittable().
It returns TRUE if the shrunk range is computed successfully and it has the length more than the value of sum of two tolerance
values of the edge (for putting vertex, as its tolerance should not be less than the tolerance value of edge) and
two Precision::Confusion() values (to make two new edges valid by Shape validity criteria).
IntTools_ShrunkRange::myErrorStatus and IntTools_ShrunkRange::ErrorStatus() have been replaced by
the IntTools_ShrunkRange::myIsDone and IntTools_ShrunkRange::IsDone(). IntTools_ShrunkRange::IsDone() returns TRUE
if the shrunk range has been computed and it has length more than Precision::Confusion().
All computations of the parameters are performed using the GCPnts_AbscissaPoint, but if AbscissaPoint is unable to
compute the parameters the Resolution of the curve is used.
2. Boolean Operations algorithm now partially works with the edges that cannot be split or does not have the ShrunkData
at all (previously such edges have been considered as micro and just ignored). If by the result of some intersection such
edges should be split, i.e. the intersection vertex should be created, the algorithm just ignores them and no vertex is created.
But if such edges coincide with other shapes (other edges or faces) the algorithm uses them for creation of common blocks.
The information of the possibility for the edges to be split is saved in its PaveBlocks, in the new BOPDS_PaveBlock::myIsSplittable field.
It can be retrieved by the BOPDS_PaveBlock::IsSplittable() or BOPDS_PaveBlock::ShrunkData(), but these methods
make sense only after filling of the shrunk data for the pave block.
BOPTools_AlgoTools::IsMicroEdge() has an additional parameter that defines whether it is necessary to take into account
the possibility for the edge to be split or not. By default it is set to TRUE, i.e. by default the edge will be considered as micro
even if the shrunk range is computed, but it is too short for the edge to be split.
3. BOPAlgo_PaveFiller::PerformEF
To avoid creation of too close intersection vertices the intersection ranges of the edges participating in Edge/Face
intersections are reduced taking into account the common ranges computed during Edge/Edge intersections.
Thus, the Edge/Face intersection vertex is not created if it gets into a common range of the Edge/Edge intersection
between that edge and one of the face's edges. The tolerance value of Edge/Edge intersection vertex is increased
to reach the Edge/Face intersection.
4. Unification of the vertices of the section edges considered as micro edges.
If by the result of some Face/Face intersection the section edge is considered as micro edge,
the vertices of this edge will be united and the edge itself will be removed.
Correction of code to avoid of usage of undefined associated parameters in order not to get exception in constructor.
